Everyone seems to be under the impression that training cards gets you lots of experience/battle points, right? Well, I had my doubts so I decided to do a little experiment. Here are my findings:
First I trained Mort Bax, a Montana 4*. It took me 7 rounds (I lost only once) and got me a total of 63 battle points (and average of only 9 BPs per battle).
If I had gotten 6 wins in a normal room (at a conservative 15 BP per battle) and 1 loss (we'll say 3 BPs), I would have netted 93!
Next I trained Globum, a Sakrohm 2*. It took me one round (a win) and I got 11 BPs. Again, in a normal room, a win would have netted me minimum 14 BPs...
Finally, I trained Vladimir, a GHEIST 5*. This one was a little more dicey, since one of my wins was a TO (so he only got 500 XP for that one) and I lost 3 and drew 1. It took me 10 rounds and netted me 72 BPs. Again, using conservative estimates, I would have received 101 BPs (6 wins @ 15 apiece, 1 draw @5 points and 3 losses @ 3 each)!!
Unless I'm missing something, I can only conclude that training is not nearly as lucrative as everyone makes it out to be. So let it be written, so let it be done!
Lets say you buy 4* prefulls (cards who are leveled to one battle away from leveling) in one battle you would get 4 cards that reach level 5, which is 40x4= 160 points plus 3 points for loss. you don't care about winning just play each card with 0 pills as fast as possible, repeat until you run out of cards/money.
In your case, you don't have prefulls I am assuming, which is why its taking so long for you.
Lost Warehouse is lucrative, or it yields lots of XP. Never both. People who grind away and bring cards to the cusp of a level up can sell them to power-levelers for a great rate of return. Folks buying 5* prefulls can clear 200XP a game and get thousands of battle points in 30-40 minutes, but it costs them an arm and a leg.
If you're not a "professional" trainer or a power leveler, the Lost Warehouse is really only useful to level up singles when you buy a 0XP card cheaply or get it in a pack and want to evolve it, or if you're buying cheap cards to sell back to Kate for the lotto and want to level them so she gives you a bigger payout.
Did you only train ONE Mort Bax?
Lets take a realistic example. You train three unleveled 3 * stars, for example 3 x Beverly.
You need 4 games to level them up, it does not matter if you win or lose. So you can play very quickly without any thinking.
--> 4 games = 84 points;
--> 21 points per game. That is not bad, especially if you have fast games!
Also, you are aware that you can train more than one card at the same time, I hope? Either with 3 nonmaxed an Vansaar or 4 nonmaxed that will level without the bonus. Your research as leveling one at a time strikes me as excessively weird. Also the assumption that you would win exactly as many fights in not-warehouses strikes me as very, very off. Many people don't really care if they win or lose in the Warehouse. I, too, would rather finish an lose 4 games played very quickly than win 2 played with "elaborate care and thought" of my opponent (read: wasting time in a totally not necessary and annoying manner) --- in the same time.
And, yeah, also pre-fulls, which I personally have never used.
First, they use prefull
like kdgns said
1 prefull will netted 40 pooints (if they use card level 4 to level 5)
you use 4 card each battle = 161 bps per battle
but this way, you will lose a lot of money since prefull is not cheap
second, in training room, you don't need to think, win or lose, your card will gain pretty good amount of exp
just play play and play
it will be harder if you play in normal room, where you need to think
and it take longer to finish a battle than in training room
You said you trained 1 card at a time right? in training room you can train 4 cards at once win or lose it will get you the same amount of xp, in normal room you can at most train 2 cards at once, not counting vansaar then you can have 2 cards that can help you win, and that's not even enough most of the time... training room is better for mass trainers
